Refactor get_uplc_type to account for constr types that don't exactly resolve to a uplc type
Check arg_stack in uplc generator has only 1 argument at the end of the generation
warning fixes
Temporarily using the 'specialize-dict-key' branch from the stdlib
which makes use of Pair where relevant. Once this is merged back into
'main' we should update the acceptance test toml files to keep getting
them automatically upgraded.
This commit also fixes an oversight in the reification of data-types
now properly distinguishing between pairs and 2-tuples.

Before this commit, we would parse 'Pair' as a user-defined
data-types, and thus piggybacking on that whole record system. While
perhaps handy for some things, it's also semantically wrong and
induces a lot more complexity in codegen which now needs to
systematically distinguish every data-type access between pairs, and
others.
So it's better to have it as a separate expression, and handle it
similar to tuples (since it's fundamentally a 2-tuple with a special
serialization).
And a few more tests along the way for others. Note that it is important here that we try to parse for a 'Pair' BEFORE we try to parse for a constructor pattern. Because the latter would swallow any Pair pattern.
Currently, pattern-matching on 'Pair' is handled by treating Pair as a
record, which comes as slightly odd given that it isn't actually a
record and isn't user-defined. Thus now, every use of a record must
distinguish between Pairs and other kind of records -- which screams
for another variant constructor instead.
We cannot use `Tuple` either for this, because then we have no ways to
tell 2-tuples apart from pairs, which is the whole point here. So the
most sensical thing to do is to define a new pattern `Pair` which is
akin to tuples, but simpler since we know the number of elements and
it's always 2.
